This editor is as far I know the most complete one built in jQuery. Regarding Ext.js the Bryntum's one is far the best I found. Here I compiled a list of available ones: http://roberto.open-lab.com/2012/06/14/the-javascript-gantt-...

Great overview! One thing that would be great to add to the overview (if you´ve still got the demo files) is how large the download is - it´s one of the things that spoke against Bryntum's solution (over 2 MB!).

Wow! I din't notice.

Looks cool! I've been working on a Gantt chart using canvas: http://beefsack.github.com/gantt.js/ The example randomly generates some JSON which builds the chart. There are still a couple of bugs, but I hope to have stable release soon. The idea was to be pretty and to minimise dependencies, currently it depends on underscore.js and XDate, but I plan to factor those out.

Your example looks cool too, but it seems a viewer only...no editing or interaction features?

Not yet, my main focus is the rendering of the chart. I plan to make an interface after the first release, but the idea is to pipe raw data into it for display rather than be interactive.

It's a pity, but the demo seems busted. It pops an alert dialog (debugging?), and then any editing seems to fail pretty quick. The screenshots look nice though :)

What browser are you using?

Same here; Safari 6 and Chrome 21 on OS X 10.8.1....

Ext Gantt is actually only 287kb, and /Mats (Bryntum founder)

I was basing that at the Example code on your site http://bryntum.com/examples/gantt-latest/examples/basic/basi... which a bit short of 2MB (at least when loaded by Safari and Chrome, it seems to load differently in Firefox)...

It would be great if you guys could show off your skills in a optimized demo site...

Here's what my Firebug Net tab tells me:

GET ext-all.js 304 OK cdn.sencha.io 442.4 KB 253ms

GET gnt-all-debug.js 304 Not Modified bryntum.com 282.4 KB 251ms

With a clean Chrome, purged cache: I get "38 requests ❘ 829.55KB transferred ❘ 1.52s (onload: 1.07s, DOMContentLoaded: 1.07s)"

And this is still without making any effort to custom build Ext JS. We're using ext-all.js for simplicity, and to make use of Sencha's CDN which should speed up world wide access compared to us hosting a custom file.

Hope this settles it :)

If your problem is due to US locale settings, the demo is set with European format, but the editor supports multiple locales. Take care also of task dependencies that can generate alerts while changing dates.
